Costco rotisserie chickens fly off the shelves extremely fast, and if you want to be first in line for a Costco rotisserie chicken, just listen for a bell.
According to employees of the retailer on YouTube, a bell sounding in the Costco deli section means that the chickens have come off the rotisserie and are about to be set out.
If you miss the deli bell or are met with a mob of Costco shoppers, don't fret. To ensure peak freshness, Costco workers put out new rotisserie chickens every two hours.
